Gel coat repair or other???

I've done a glass transom build up on my CC. three layers of glass. Stripped the form and glass bondo the joint. I've sanded it down but I'm not really sure what to finish with. I thought I would gel coat but I can't find anything but gel coat repair kits. I've got an area about 60" wide by 6" that are now bondo. Any ideas?
I'll add my ongoing photos to my gallery when I get home from work on Wed.
